# Crypto-Vinaigrette
[]()
[](https://github.com/aditisrinivas97/Crypto-Vinaigrette/blob/master/LICENSE)
A quantum resistent asymmetric key generation tool based on the rainbow scheme for digital signatures.
## Why would you need this?
Digital signatures are a common way of authenticating a sender by verifying a piece of information attached to the document. In our case, the attached piece of information is a sequence of numbers generated using the document which is to be signed.
As mentioned before, we employ the Generalised Unbalanced Oil and Vinegar scheme or the Rainbow scheme to achieve the same.

## Installing
To build and install cryptovinaigrette, run the following commands
```
$ git clone https://github.com/aditisrinivas97/Crypto-Vinaigrette
$ cd Crypto-Vinaigrette
$ python3 setup.py install
```
Or install the package using pip (Pending..)
```
$ pip install cryptovinaigrette
```
## Usage
1. Creating a key-pair.
The keys generated are stored in the directory passed as parameter to generate_keys.
```python
from cryptovinaigrette import cryptovinaigrette
# Initialise keygen object and generate keys
myKeyObject = cryptovinaigrette.rainbowKeygen(save="/path/to/dest/folder")
```
2. Signing a document.
Signing is done using the `Private Key`. Assuming the private key is named `cvPriv.pem` and the document to be signed is `testfile.txt`,
```python
signature = cryptovinaigrette.rainbowKeygen.sign('cvPriv.pem', 'test/testFile.txt')
```
3. Verifying the digital signature.
Verification is done using the `Public Key`. Assuming the public key is named `cvPub.pub` and the document whose signature is to be verified is `testfile.txt`,
```python
# Case where signature is valid
check = cryptovinaigrette.rainbowKeygen.verify('cvPub.pub', signature, 'test/testFile.txt')
# Case where signature is invalid
check = cryptovinaigrette.rainbowKeygen.verify('cvPub.pub', signature, 'test/testFile2.txt')
if check == True :
print("Verified successfully!")
else :
print("Signature does not match the file!")
```
